So here is my question of the day... What is the average interior decibels you guys are getting at highway cruising speeds (60-70mph, AC Off, radio off no conversation) that are running any brand of catless DP, I am looking for some data with catelss DP and stock exhaust preferably. I will take data from aftermarket exhaust as well. Also if anyone wants to help capture this data if you have an iPhone can get a free decibel meter app and I would assume the same on android platform as well.

I have AR catless dps and the hpf gen 2 exhaust and I thought I was going to lose my mind for the first few days. The drone was beyond ridiculous. Between 2500 and 3k rpm at 80 mph fuhhhgettaboutit. It's been 2 weeks now and I'm getting use to it. I even contemplated getting rid of the exhaust but it sounds soooooooo freaking sexy from the outside lol. Best sounding exhaust that I've ever heard from the outside of the car. Upon acceleration or wot its pure sex. Only negative is that drone on the inside between 2500 and 3000. Hope this helps! Lol

+1 love this setup

Just catless downpipes won't change cruising volume by any noticeable amount at all but it will add a little rasp when WOT
